How this service works
x402 pay-per-call. Payments are per request in USDC and are final. No refunds on-chain. Service is provided as-is and may change or stop without notice. Informational data only, not financial, investment, legal, or tax advice. Metrics such as net transfer volume estimates and wallet clusters are algorithmic estimates from public blockchain data and may be wrong or delayed. Provided as-is with no warranty. Methodology: https://crypto-data-api-zo95.onrender.com/methodology.
Output
A JSON object containing the requested time window, per-token metrics (transfer count, gross_volume, circular_share_estimate, non_circular_volume_estimate), a summary transfer_volume block, pipeline freshness checks (checks_run array), a plain-text volume_definition, a generated_at_utc timestamp, and a disclaimer. Diagnostic fields like raw_transfer_volume and intra_tx_round_trip_volume are also included.
Example use cases
Real-time Base stablecoin activity dashboard
“Pull the last hour of stablecoin transfer volume on Base for me, including how much is circular versus genuine economic activity, so I can update our live dashboard.”
Bot churn analysis for Base stablecoins
“What share of stablecoin volume on Base over the past 6 hours looks like bot round-trips or circular flows rather than real transfers?”
24-hour stablecoin volume trend report
“Give me the full 24-hour stablecoin transfer volume on Base, including gross volume, the non-circular estimate, and a per-token breakdown, so I can include it in today's DeFi report.”
Technical details
Endpoint
GEThttps://crypto-data-api-zo95.onrender.com/v1/base/stablecoin-volume?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need current or recent on-chain stablecoin transfer volume specifically for the Base blockchain, with circular-flow deduplication built in. It is distinct from DEX trading volume APIs and is best suited for DeFi analysts, dashboard builders, or agents that need economic transfer activity (not swap volume) at 1h, 6h, or 24h granularity. Prefer alternatives if you need Ethereum mainnet, Solana, or other chains, or if you need historical time-series beyond the rolling window.
Side effects
- Payment not submitted or rejected — endpoint returns HTTP 402 requiring USDC payment via x402 protocol
- Invalid window value (not 1h, 6h, or 24h) — likely returns a 400 or validation error
- Data pipeline lag exceeds 300 seconds — checks_run will show pipeline_fresh as failed
- Service unavailability (hosted on Render free tier) — possible cold-start latency or 503 errors
- Stale or delayed data — algorithmic estimates may not reflect real-time chain state
